OPGW Tension Clamp

Specifications

Thank you for you to pay attention to my product ,If you want to know more about ,pls see under;If you have any requires ,pls without hesitate contact me 

opgw tension clamp

1.It has big grip and high safety performance ,it is used in electric line of steel strand wire ,aluminium strand wire ,steel-core aluminium wire and insulated conductor etc.The grip of helical strain clamp could reach to 100% strand wire  calculated dragging force at break or above.

2.The tension clamp has good corrosion resistance .the material is same with conductor, which could ensure the clamp has strong anti-electrochemical corrosion capacity.

Shackle:Hot galvanized steel shackles play a role in connection with the tower fasteners. Failure load: U-7 to 70kN, U-10 to 100kN, U-12 to 120kN.

Thimble:Hot dip galvanized steel precision thimble, in the U-shape bending head, which can make tension clamp connect with exstrain rod.

Preformed tension rods:Be made of galvanized steel wire or aluminum clad steel and preformed into the process when prefabricated beam, inner wall layer of emery stick, and enhance the friction between clamp and cable. 

Preformed armour rods:Galvanized steel or aluminum clad steel wire, preformed armour rods wall sticky particulate silicon carbide to increase friction and reduce the pressure on the cable side. preformed rods  when the pre-processing into several sub-beams, to avoid installation errors and to facilitate rapid installation. Preformed wire toward the end of different specifications according to the radial lateral bending, to avoid vibration in the breeze under the cable clamp at the end of the friction and prevent damage to cable extrusion.
